PAPER RECEPTACLE Specification of Letters Patent.

application filed January 17,1912. Serial No. 671,637.

To all whomit mag concern:

Be it known that I, 'Ciunnrs T. BLOOMER, a citizen of the United States,residing at Newark, in the county of W'ayne and State of New York, haveinvented a new and "useful Paper Receptacle, of which the fol lowing isa specification. TlllS invention relates generally to receptaclesconstructed of paper or other suitable material and particularly tomeans for locking the cover flaps of the receptacle in closed position.a v

The present'invention can be used'as a locking means for all kinds ofpaper receptacles including ice' cream boxes, oyster pails, as well asother types of folding-flap receptacles not. necessary'to specify.

. The principal object of the present invention is to provide means foreasily and quickly locking the receptacle in closed condition in suchmanner that the-cover flaps shallbe held positively against bulging, and

that the receptacle shall be capable of being easily and quickly openedwithout being capable of accidentally swinging open.

A further. object of the invention is to effectv a material saving inpaper stock,

equivalent to or exceeding in cost the metallic attachments employed inthe present invention', whereby the cost of receptacles constructedunder this invention is practically the same or lower than the cost ofold forms of receptacles which are open to the pbjection that they areliable to bulge and accidentally open.

\Vith the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in theembodiment of the invention herein disclosed can "be made within thescope "of whatis claimed, without departing from the spirit of theinvention.

In the accompanying drawing forming a part of this specification: Figure1 is a perspective view of a receptacle constructed in accordance withthe present invention, the locking flaps being opertyFig. 2 isaperspcctivc viewshowing the flaps folded into closed position, thefolded or creased portion of the tabbed flap being folded under thetongued flap, the tongue of the latter .fiap projecting through theopening in the 'tab of the former flap preparatohv'tobendthe drawing.

ing the tongue to-lock the receptacle; Fig. 3 is a view similar to Fig.2 showing the tongue folded into locked position," Fig. 4: is a verticalsection through the construction illustrated in Fig. 3, showing theparts in locked condition.

Like reference numerals indicate corresponding parts in thediflerent.figu resof The body .1 of the receptacle may be .con-

.structed in any spitable manner, such as by pasting, in the case of anice cream pail, by folding, in the case of an oyster pail,- or byotherwise arranging the blank, in accordance with the various practicesof the art. The body 1 preferably is provided with upstanding side flaps1' and 2, which are designed to be folded inward toward each other.

The reference numeral 3 indicates the tongnetli flap "and the referencenumeral 4 indicates the tabbed flap. The ton ue of' the flap 3 isindicated by the numera 5 and consists preferably of a metallic striphav- -ing the clenching points or members 6. de-

signed to be clenched through the flap '3,

-as shown in Fig. 1. The fla'p 4, is formedwithin the contour thereofwith a tab 8 which preferably, although not essentially, issubstantially rectangular in shape and is separated from the flap onthree sides, bein joined to the flap on what may be terme its basal ede. Tie means for separating the tab 8 rom t e flap 4 on three sidespreferably comprises the slotted portion 9. The slotted portion 9 isused in preference to a knife slit, as it serves to effect a complete,

separation of the edges of the tab 8 from the adjoining portions of theflap 4. The outer end portion of the tabbed flap 4; preferably iscreased along the dotted lines 1010, so as to facilitate its bendingalong said lines. It will be noted that the dotted lines 10 are inalinement with the basal portion or edge of the tab 8. Said basalportion of the tab 8 is uncreased, as shown. The tab 8 isformed with acut away portion or tongue opening 11 which preferably is tapered inform, as shown,- thewide portion of said opening ll being substantiallyin alinement with the creased portions 10, although this location of theopening is not essential.

Particular attention'is directed to the fact Patented Aug. 26,1913.

while the flap 4' is relatively long, both of the flaps have their freeendsterminating" the tab 8 of said flap eiprojecting on the outside ofsaid. tongued fiap 3. The tongue .5 of the flap 3 when the outercressed'portion of the flap 4 is first fitted under the flap 3, isdirected through the tab opening 11. By pushing downward on the top ofthe box, the flaps assume the position illustrated inFig. 2, with thetongue 5 projecting through the tab opening, the creased portion' i' ofthe flap ibeing disposed underneat-h the -fiap'3, and the uncreesed tab8 projecting on the outside of the iiap 3. i It is. new only necessaryto slip t-he finger beneath the tongue 5 andbend it over into theposition illustrated in Fig. 3 of the 30.dra wing.' 4 v -=An lmportantfeature results from the provision'of fold'lines extending from the endso'f'the U-shuped slit forming the tab to the sideedges of the flap 4, inthat, when the flaps 3 and 4- are closed or folded over the mouth of thereceptacle, the tongue 5 may be passed or projected through the aperture.01 opening 11 of the tab without bending either the tab or tongue. thefree 40 end of the tabbed flap-4 being flexible or .foldable awayiromthe tab for this purpose. In a.v device ofithis character-it isessential that the tab beassmail as possible, itbeing noted that thebaseor butt end of the-tab 8 is weakened by the aperture or opening 11, andit is therefore desirable that the tab ,remain unfolded or unereased.With the present arrangement, it will be clearly appa-rent that-the tab8 remains in the plane of the flap {t under all conditions, and is notfolded or bent, the tongue 5 being adapted to pass through the tabwithouteither of them being folded or bent. The tongue 5 is only bentafter the flaps 3 and 4 are in position, so that the tab 8 will be ofthe greatest strength possible, as is essential.

The free endor portion of the fliip' 4 is readily flexible or foldableawe. from the tab 8 to permit of the insertion o the tongue'- 5 throughthe tab in the manner specified; The locking means of'the resentinventipn are strong, -smiple, dura le and inexpensive in construction,as well as thoroughly" practical and efiicient in operation.

The locking device can be readily unloclredby bending up the tongue 5. 1When the tongue 5 is bent on itself in the manner indicated, it, engagesthe. narrow endof the tapered. tongue opening and thus centers,

itself properly in the tongue opening with-- out being permitted to movesldewise rela. tively to the opening.

The tapered o" ening 11, which has its edges diverging rom the free endof the tab 8, is of advantage, for the reason that the larger orinnerend of. the opening 11..

permits the tongue to be readilyinserted therethrough and then bentback, firedgend will work outwardly between the edges of the opening 11and will thus bring both of the flaps 3 and 4 in pro er positionrelative to each other. Thus, although only the free ends of the flaps 3and 4 are overlapped,

both of the said flaps will be locked against lateral shiftingmovements. The provision of the tongue 5 carried by the free endoi theflap 3 and the provision ofthe tab 8 at the free end of the flap tprovides for a saving of stock, and also permits the flaps to be lockedin engagement in sueha' manner as to prevent shifting movements eteither flan.
